Servant or Slave?

This applies to so many things in life: marriage, jobs, relationships, getting healthy, etc. 

I got this from John Bevere's Bait of Satan curriculum and thought it was pretty good. 

A slave: has to. 

A servant: gets to. 

A slave: does the required minimum. 

A servant: does the maximum potential. 

A slave: forced to go 1 mile. 

A servant: choses to go 2 miles. 

(Matthew 5:41)

A slave: feels robbed. 

A servant: gives freely. 

A slave: fights for his rights. 

A servant: lays down his rights for the sake of others.
